Maximum size of volumetric window on visionOS?

I'm loading in USD content through RealityKit on visionOS. I'm computing the bounds of the model and increasing the view and window size to match the USD size. Larger models are getting cut off. Through experimentation - it seems like volumetric windows have a maximum 2 meter size in any dimension. This seems reasonable - but is this expected behavior? If so - is it documented anywhere so I can guard against this case? I just want to make sure this is indeed true so I can stop troubleshooting my view hierarchy.
